IVILLIAIII L. CHASE, OF BOSTON, MASSACHUSETTS.

IMPROVEMENT IN FASTENING THE SHOES 0F HlLLSlDE-PLOWS.

Specification forming part of Letters Patent No. 7,518, dated July 2Q,1850.

To all whom t may concern:

Be it known that I, WILLIAM L. GIIAsE, of Boston, in the county ot'Suffolk and State of Massachusetts, have invented certain new and usefulImprovements in Hillside Plows, of which the following is a full, clearand exact description, reference being had to the accompauying drawingsof the same, making part of this specification, in which Figure l is aview in perspective of theland side of a plow having my improvementapplied thereto. Fig. 2 is a section through the line .r m of Fig. 1,and Fig. 5% is a view in perspective of the shoe or runner detached fromits place on the lower edge of the landside.

My invention and improvement consists, first, of a shoe or runner sofitted to the lower edge of the landside that it can readily be removedtherefrom to be replaced by another when worn, broken, or for any causeit is re quired to remove it, this removable shoe'being ltted witheither sockets or pivots at its ends, to which the mold-board isconnected and on which it turns. By this arrangement, when a socket orpivot on the landside is broken or worn the damage can be repaired bymerely removing` the shoe and replacing it by a new one, constructed inthe ordinary manner, with the shoe and handle and beam, and standardscast in one piece with them, without dis turbing the other parts of theplow; but the whole landside would have to be thrown away and a new oneput in its place in the case or hillside plows as ordinarilyconstructed, with the standards, shoe, and pivots all castin one piece.Besides the expense incurred by throwing away so large a piece ot'casting, the handles and beam have to be disconnected from thestandards, which consumes a good deal of time, and is productive ofgreatinconvenience, as the plow has to be taken to pieces and puttogether by farmers, who are neither conversant with such mechanicaloperations nor possessed of the requisite tools to perform them withfacility.

The second part of my invention consists in making the landside with twofaces, but otherwise shaped and proportioned like the landside of theordinary plow for working the level land, that-turns the furrows in onedirection only. By thus making the landside with two faces it will workequally well with either side to the land, and by making these faces aswide as the face ofthe landside of the common plow it will work quite assteadily as the latter in level land, with the advantage that it willturn the furrow to either the right or left at the option of theplowman.

lIhe ordinary skeleton landside ot thehillside-plowisohiectonable,becauseitisconstantly becoming clogged withstones, roots, sods, weeds, Sac., the lodgment of which it favors, whilethe construction of my landsideis such that it is scarcely possible forany ot'these obstructions to ell'ect a lodgmeut on it, and consequentlyit avoids the great increase of friction that takes place when the roughsurface ofstones,roots, sods, or earth has to be dragged over thesurface of the land instead ofthe polished metallic surface, which myplow always presents.

In the accompanying drawings, Figure l represents the landside A withthe beam-standard a and the standard b, to which the handles of the ploware attached, broken oft'. The lower edge of the landside has a shoe, B,fitted to it, and on its front end a cutter, d, is placed. To the recessbeneath the cutter d the share and moldboard are litted. The lower edgeof the mold-board is dovetailed, and it tits in a groove ofcorresponding shape in the upper side of the shoe, as seen in Figs. 2and 3, the shoe sliding on the ylower edge of the landside from theiront end ofthe latter. The groovein the shoe terminates at a shortdistance from its front end, theend ofthe groove shutting up against ashoulder formed on the lower edge of the landside to prevent the shoefrom being forced backward by the resistance ot't'ered by the earth tothe passage of the' plow through it. On the front end of the shoe apivot, c, is formed, and at its rear end a socket is formed ofcorresponding shape. A socket on the rear end of the landside of theshare, on the under side of the mold-board, ts over the pivot C, and apivot on the inner end of the main brace of the win g of the mold-boardfits into the socket at the rear end of the shoe. By this means themold-board and share are connected to the landside.

Having thus described my improved landside, what I claim therein as new,and desire to secure by Letters Patent, is-

The device for attaching and detaching the removable shoe, having themold-board hinged to it and being fastened to the landside,substantially as herein set forth.

In testimony whereof I have hereunto subscribed my name.
